INTRODUCE The aim of the study was to determinate the effect of low X-ray doses on the percentage and number of peripheral blood lymphocytes T (CD3+), T helper (CD4+), T cytotoxic (CD8+), lymphocytes B (CD19+), activated T lymphocytes (CD3+CD25+) and activated T helper lymphocytes (CD4+CD25+) as well as serum immunoglobulins (IgM, IgG and IgA) concentration in workers of an interventional cardiology ward. MATERIAL AND METHODS The study was performed among a group of 40 workers (28 women and 12 men) and a control group of 35 persons (25 women and 10 men). Flow cytometry was used for the analysis of lymphocytes and the turbidimetric method for assessing serum immunoglobulin concentrations. RESULTS The study showed a decreased percentage and number of CD3+CD25+ and CD4+CD25+ cells as well as IgG concentration in interventional cardiology ward staff in comparison to the control group. A negative correlation between the length of employment and percentage of CD3+CD25+ was found. CONCLUSION The study indicates suppressive impact low doses of ionizing radiation on activated T cells, activated T helper cells as well as IgG production that is adverse in relation to the existing risk of infections caused by different microorganisms.
